C++ source code is available to provide example code of processing S-Records and converting them to
NovAtel format commands, as well as providing help with the SoftLoad process. Contact

S0, S5 and S7 S-Records should be sent directly to the receiver using the
by enclosing the S-Record in quotation marks and issuing the command to the receiver, as follows:

S3 records can be sent individually to the receiver using the

only a small number of bytes of firmware data. A single
4096 bytes of firmware data from multiple S3 records, whereas a single

Multiple S3 records can be packaged into a single
one S3 record follows immediately after the previous record.That is, the address from the current S3
record must equal the address from the previous S3 record plus the data length of the previous S3
record. If the data is not consecutive then the
of data it has packaged up to that point. Subsequent data can be packaged in a new
command. Within the

The *.hex and *.shex file data may contain many gaps and jumps. For example, in many NovAtel *.hex
and *.shex files, data for address 0x000_00000 is stored near the very end of the file.
